Diagenesis does not invent anything new: Precise replication of conodont structures by secondary apatite

Autor: Annalisa Ferretti, Daniele Malferrari, Luca Medici, Martina Savioli

Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-9 (2017)

Abstract Conodont elements are important archives of sea/pore water chemistry yet they often exhibit evidence of diagenetic mineral overgrowth which may be biasing measurents. We decided to investigate this phenomenon by characterising chemically and

We investigated the mineralogical and chemical signatures of enigmatic microspherules commonly recovered in conodont residues and referred to in literature as 'conodont pearls.' Comparison between these 'pearls,' associated conodonts and other phosph

Bioapatite is probably the key factor in the unreplicated success of vertebrates. Chemical data on bioapatite composition can be achieved on a solid sample by using different analytical tools such as spectroscopic and spectrometric methods. As analyt

Calcium carbonate, silica and calcium phosphate have been selectively used by organisms in the production of mineralized hard parts throughout the Phanerozoic. Among these materials, bioapatite has enabled fundamental acquisitions in the evolution of

Zooming in REE and Other Trace Elements on Conodonts: Does Taxonomy Guide Diagenesis?

Conodont elements are calcium phosphate (apatite structure) mineralized remains of the cephalic feeding apparatus of an extinct marine organism. Due to the high affinity of apatite for rare earth elements (REE) and other high field strength elements

Unravelling the ultrastructure and mineralogical composition of fireworm stinging bristles

Autor: Sara Righi, Roberto Simonini, Daniela Prevedelli, Martina Savioli, Daniele Malferrari

Publikováno v: Zoology (Jena, Germany). 144

Amphinomid fireworms are notorious for their stinging dorsal bristles (notochaetae), but it is still unclear whether the irritation they cause is merely mechanical or if the notochaetae contain toxins. Furthermore, although fireworm chaetae have alwa

Response to Tilic and Bartolomaeus’s Commentary on the original Research Paper 'Unravelling the ultrastructure and mineralogical composition of fireworm stinging bristles' (Zoology, 144)

In their Commentary to our paper recently published in Zoology (Righi et al., 2021a), Tilic and Bartolomaeus question our findings that the chaetae of Hermodice carunculata (Annelida) are hollow and able to store and deliver venoms. They sustain the

Bioapatite represents an important acquisition in the evolution of life, both in the seas and on land. Vertebrates applied calcium-phosphate biominerals to grow their skeletal support and to shape their teeth, while some invertebrates sheltered their
